STPS50U100C
ULVF™ power Schottky rectifier
Features
ultralow forward voltage drop
high current capability
high frequency operation
Description
The STPS50U100C is a dual power Schottky
diode rectifier, suited for high frequency switch
mode power supplies.
Featuring an ultralow forward voltage (ULVF)
drop, this device, packaged in TO-220AB and
I
2
PAK, is intended to be used in notebook, game
station and desktop adaptors as well as server
SMPS. It has been especially designed to help
power supply manufacturers meet the recently
introduced worldwide efficiency standards.
